Stay safe on the roads this morning. Leave extra space between the vehicle in front of you, and never drive through standing water. View storm safety tips: bit.ly/3jweiLj

712am Radar📡: Pockets of moderate to heavy rain will result in a tricky morning commute for the Bay Area and parts of the Central Coast. Be sure to use caution and allow extra drive time to work or school. Gusty winds of 35 mph should be expected within the heavier rain. #cawx
